21291843 ÷ 892 
We're looking to find how many times 892 goes into 21291843.

Let's proceed to step 1:
The number 892 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 892

Step 2:
When dividing 21 by 892, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 892

Moving on to step 3:
892 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Append the next digit (9) from the dividend to 212 and continue with: 2129 / 892

Moving on to step 4:
892 can be fit into 2129 2 times, resulting in a remainder of 345.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1784 from 2129 and we're left with 345.
Append the next digit (1) from the dividend to 345 and continue with: 3451 / 892

On to step 5:
If we divide 3451 by 892, we get 3 and a remainder of 775.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 2676 from 3451 and we're left with 775.
Grab the next digit (8) from the dividend, add it to 775, then carry on: 7758 / 892

Moving on to step 6:
When dividing 7758 by 892, we get 8 with a remainder of 622.
Use 8 as the next digit of our solution. 
Result so far: 238.0
If we subtract 7136 from 7758, we get 622.
Include the next digit (4) from the dividend after 622, then repeat: 6224 / 892

Going ahead to step 7:
892 goes into 6224 6 times with a remainder of 872.
Put 6 as the next digit of the answer. 
Result so far: 2386.0
Deduct 5352 from 6224 and we're left with 872.
Append the next digit (3) from the dividend to 872 and continue with: 8723 / 892

Advancing to step 8:
892 goes into 8723 9 times with a remainder of 695.
Put 9 as the next digit of the answer. 
Result so far: 23869.0
Subtracting 8028 from 8723 leaves us with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Going ahead to step 9:
892 can be fit into 6950 7 times, resulting in a remainder of 706.
Use 7 as the next digit of our solution. 
Result so far: 23869.7
If we subtract 6244 from 6950, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 10:
892 goes into 7060 7 times with a remainder of 816.
Record the quotient 7 as the next digit in the result. 
Result so far: 23869.77
If we take 6244 away from 7060, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

The final result is 23869.77 with a remainder of 0.816.
